HENRY L. ROOKE, JR,

OF HOUSTON, TEXAS.

PBOEECTING-CASIN G FOR ELECTRICAL CONDUCTORS.

Application filed May 1, 1917.

To all whom it may concern:

Be it known that I, HENRY L. ROOKE, J12, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Protecting-Casings.

for Electrical Conductors, of which the following is a specification.

This invention relates to new and useful improvements in a protecting casing for electrical conductors.

The object of the invention is to provide a device of the character described particularly designed for surrounding the commutator of an internal combustion motor and protecting the terminals thereof and the electrical conductors connected to said terminals.

As is well known, internal combustion motors are usually provided with commutator-s through which the ignition is controlled. These commutators are provided with terminals or binding posts to which the electrical conductors are connected and unless protected these terminals and conductors will collect oil and other foreign matter causing the electrical current to short-cirt is the object of this invention to provide a-protector for said terminals and conductors to prevent the collection of oil and other foreign matter upon them.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure l is a plan view of the device applied to a commutator,

Fig. 2 is an edge view thereof partially in section, and

Fig. 3 shows a plan view with the outer section of the protector removed.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refersto a commutator of a well known type which is in common use upon the motors of Ford automobiles. The body of this commutator is cylindrical in form and has the radiating terminals or binding posts 2 connected thereto in the well Specification of Letters Patent.

known manner and from these terminals lead the electrical conductors 3 said conductors usually being protected by a surrounding sheath in the well known manner. Surrounding the cylindrical body of the commutator is a fiber casing composed of sections 1', r, said casing fitting closely over the body of the commutator and the sections thereof being secured together by means of the bolts 5. The'adjaccnt sides of the sections of this casing are provided with annular grooves G. (3', said grooves coinciding when the sections are fitted to ether, as shown in Fig. forming an annu ar space for the electrical conductors and said sections are likewise provided with internal sockets to receive the corresponding termi- 1 nals 2 which fit the-rein so that when the sections of the casing are secured together in position on the commutator, they completely inclose and protect said terminals and conductors. The casing l is provided with a hollow neck 7, integral with, but upstanding from said casing and the four electrical conductors pass out through this neck and are protected by it and beyond the neck 7 said conductors are protected by the usual flexible metallic sheath in the well known manner.

What I claim is:

The combination with a commutator having radiating terminals and electrical conductors connected to said terminals, of a casing ring like in form, said casing fitting closely over the body of the commutator and being formed of sections, the sections thereof being secured together, the adjacent sides of the sections being provided with annular coinciding grooves forming an annular space to receive the electrical conductors and being also provided with internal sockets to receive the corresponding'terminals and a hollow neck carried by said casing through which said conductors pass.

In testimony whereof I have signed my name to this specification in the presence of two subscrih log witnesses.
